In former times people dug tunnels into mountains to mine precious metals. Nowadays in Germany more than the half of the processed cupper is recycled.

A multilevel shredding with sharp knives and a subsequent compartmentation enables a straight separation of the plastic coating and the cable cores made of precious metals. Here especially rough conditions exist for the material and machine. A machine knife in the cable recycling industry needs to cleanly cut big underground cables but also filigree single conductors.

Our high performance steel knives stand up to exceptional requirements, since they are sharpened precise down to just tenths or hundredths of a millimeter.
